Abstract

The paper presents the case history of the geotechnical characterization of a seismic site for the re-use of an industrial building for producing solar panels in the industrial area of Catania (Sicily, Italy). To determine the geological profile and the geotechnical characteristics of the soil, the site was well investigated by means of in situ and laboratory tests. The following in situ geotechnical tests were carried out: Borings, SPT, CPT, PLT and dynamic in situ tests. Among them Down-Hole (D-H), Cross-Hole (C-H), SASW and recently Seismic Dilatometer Marchetti Tests (SDMT) have been carried out, with the aim to evaluate the soil profile of shear waves velocity (Vs). Moreover the following laboratory tests were carried out on undisturbed samples retrieved with a 86 mm diameter Shelby sampler: Oedometer tests, Direct shear tests, Resonant Column and Torsional shear tests. Static and dynamic parameters obtained by in situ and laboratory tests were reported and analyzed. Moreover the Sicilian earthquake of December 13, 1990 (ML= 5.4) heavy damaged the site, also due to soil amplification. Using the recordings of this earthquake, to evaluate the input motion at the conventional bedrock, the ground response analysis has been obtained by the 1-D non-linear code EERA at the industrial building site. In particular the study has regarded the evaluation of site effects in terms of acceleration time history at the surface, soil amplification factors, as well as in terms of time history and response spectra.

Site Response Analysis in the STM-M6 Industrial Area of the City of Catania (Italy)

Chicago, Illinois

The paper presents the case history of the geotechnical characterization of a seismic site for the re-use of an industrial building for producing solar panels in the industrial area of Catania (Sicily, Italy).
